March 30, 1937. 6.7M. FINKES TOOL HANDLE Filed April 1, 1955 2 Sheets-Sheet 2 Patented Mar. 30, 1937 UNITED STATES PATENT OFFICE TOOL HANDLE Application April 1, 1935, Serial No. 14,090

10 Claims.

This invention relates to an improved tool handle of the type employed in connection with shovels, spades or the like, and it is a primary object of the invention to provide a handle of the socalled Y type having a pair of tubular sheet metal arms, the said arms having their outer ends connected with a non-rotatable transverse grip and having their other or inner ends joined to form a non-welded stale receiving socket, provision being made for uniting the separable metallic arms of the handle in temporarily secured relationship prior to the application of the handle to the end of a tool stale.

It has been customary in the manufacture of tool handles of the type referred to to form the same to include sheet metal arms joined at their lower ends to provide a stale socket but in such prior art handles, it has been the practice to weld the adjoining edges of the arms together so that the arms in effect become an integral open-piece construction. This accepted practice results in the formation of stale sockets of fixed and unchangeable diameter, with the result that considerable difficulty and expense are incurred in the matter of fitting the stale ends into such sockets, particularly when there are variations in the diameter of the Wooden handles or stales or in the receiving sockets therefor provided in the joined and Welded sheet metal arms.

As a matter of practical manufacture, it is important that the sheet metal arms be joined and united with the transverse grip at the upper or outer ends of said arms, prior to the application of the handle as a whole to the upper end of a stale, and this has led to the practice of welding the arms along their points of juncture at the stale receiving end of the handle.

In accordance with the present invention, I

provide a Y handle composed of hollow sheet metal arms which are united by mechanical fastening means and wherein the step of welding has been entirely omitted, whereby through the employment of such mechanical fasteners, I am enabled to assemble the arms and transverse grip of the handle and hold the same in such assembled relationship before the handle is secured to the end of a stale and further, I provide the stale receiving ends of the arms with registering openings for the reception of a plurality of fastening rivets which pass through said arms and through the stale insert in the socket afforded by said arms, so that the adjoining edges of the arms may remain slightly spaced to provide for variations in the diameter of the stales associated with the handle and also to overcome any looseness which may develop after some use of the tool on which the handle is provided. '1

Another object of the invention resides in providing the meeting edges of the tubular sheet metal handle arms at points where the stale receiving socket is produced, with inwardly directed longitudinally extending ribs or flanges, the latter being received within corresponding grooves provided in the upper ends of the tool stales, whereby when the arms are finally riveted in connection with such stales, a strong and substantial con struction will be produced providing for a firm union between the handles proper and the stale as connected therewith.

For a further understanding of the invention,

reference is to be had to the following description.

and the accompanying drawings, wherein:

Fig. 1 is a view in front elevation, and partly in vertical section of a tool handle constructed in accordance with the present invention;

Fig. 2 is a transverse sectional view taken through the handle on the plane indicated by the line 11-11 of Fig. 1;

Fig. '7 is a detail sectional View on the plane indicated by the line VII-.-VII of Fig. 2.

In the specific form of the invention trated in the accompanying drawings, the tool as illus handle Ill is formed to comprise a plurality of hollow, complemental, sheet metal arms H-l I. As shown in Fig. 6, each of these arms is formed from a sheet metal blank 12 and which includes a substantially rectangular lower region l3, provided with vertically spaced, centrally situated openings I i. Ihe region I3 terminates at, its upper end in a widened area l5, which is marginally shaped or stamped to provide an integral tongue it on one side thereof and a complemental recess ll on its opposite side. Above the area IS, the blank is provided with upwardly converging side edges I8, which terminate in a substantially circular head portion IS, the latter being aper-H,

tured as at 20 and additionally provided with hOT-Y izont'ally spaced semi-spherical depressions 2 l Through suitable forming operations, each of theseblanks is bent so that the resulting arms produced thereby, when properly mated, as shown in Fig. 1, form a handle possessing a Y-shaped configuration. In addition, each blank is bent 5 so that the lower region l3 thereof will be provided with a substantially vertical stale-receiving socket 22 of semi-circular cross sectonal form, each socket 22 terminating in vertically disposed, inwardly directed ribs or flanges 23 which mate or register with similar ribs or flanges provided on the opposite or complemental arm, the combined sockets 22 of said arms being substantially circular in form for the reception of a tool stale 4 lBefore the stale 24 is inserted in the handle sockets thus'provided, the .arms H are mechanically joined without welding through the provision of the tongues it, which are upwardly bent to interlock with the recessed portion H of the complemental arms, so that'separation of the lower portons of said adjoining arms. will be prevented. The union between said arms secured by the interlocking tongue I6 is a relatively loose one and permits of some relative 25 movement between the adjoining lower portions of the arms il so that the stale receiving socket will be adapted to readily receive stale ends varying slightly in diameter. This is an important practical consideration since heretofore it has been the customary practice to unite through welding the adjoining lower portions of the metallic arm stampings, with the result that sockets of'fixed diameter are produced and are incapable of responding to variations in the diameter of the interfitting stales. This often results inunde- .sirable looseness between the handles and the "stales or again in causing breakage and structural imperfections in the handle when oversized stales are forced into such sockets. Again, 40 at the time of inserting the stales into the handle sockets', a welded socket may provide for accurate fitting, but when the wooden stales dry during storage, handlingor transportation, the resulting'shrinkage causes looseness. To avoid these difliculties and manufacturin problems, I unite the handle arms through the medium of the relatively loosely engaging tongues or prongs [6 which in connection with the transverse grip 25, at the upper end of the handle, provide for a complete handle unit which may be manufactured, assembled and stored independently of the tool stales and connected with said stales to form the completeand finished tool whenrequired, with precisely the same facility as can be obtained with the welded construction, but by avoiding the welding step and r leaving the lower ends of'the arms susceptible to a limited degree of relative adjustment, the

handle iswell adapted to "receivestales produced under accepted standards of manufacture, which admit of some variation in diameter.

' At the time of assembly, the stales have their upper ends grooved as at 26 for the reception of the registering ribs or flanges 23, which are received within said'grooves when the stales are forced or inserted into the sockets formed for V the reception thereof in the lower ends of said arms. The union is made complete and efiective by theemployment oftransverse rivets or other equivalent fasteners 21, which pass through the sp'aced vertical openings l4 and also through "corresponding horizontal openings provided in the upper ends of the stales. When the rivets are headed, pressure is applied to the lower ends of the arms H, drawing the latter into firm se- 2,o7'5,277 I V o curing engagement with the upper ends of said stales. Then, if the stales should shrink either before sale of the tools or afterwards, it is a,

simple matter to overcome the resulting looseness by merely again tightening the rivets or fasteners 21 to the required degree.

Above the stale receiving sockets, each of the arms H has imparted thereto a compound curvature and in cross section possesses an oblate hollow configuration, the meeting edges thereof beingjoined along the inner sides of said arms. The converging side edges I8 of the blank I2 cause the arms when finally finished to taper progressively from the lower to the upper ends, thereof. In addition to this taper, each of the arms is bent to produce a compound curvature disclosed in Fig. 1 so that the joined or secured arms will possess the Y or D form well known in the art.

The transverse grip 25 is preferably of wood and has its opposite longitudinal ends reduced as at 28 and positioned within substantially circular sockets 29 formed in the head portions l9 of said arms. These elements are fastened -.to-'-. gether by a longitudinally" extending -;rivet 30,

which passes through the wooden grip 25 inoffset relationship to thetrue axis of the grip,-

the ends of the rivet 30 being received within the apertures 20 of said arms. are headed, as usual, to maintain V N terminal portions 28 of said grip'seatedwithin the sockets 29 and in secured but non-rotatable engagement with the upper ends of the metallichandle arms. In order to positively avoid rotation of the handle grip, the semi-spherical depressions 2| of said arms are positioned within correspondingly shaped pockets 3| formed in the end surfaces of the grip 25, the depressions 2| entering the pockets 3| and are retained therein by the bolt or rivet 30 so that turning of the grip will be effectively prevented.
